    Urban fiscal austerity, infrastructure provision and the struggle for regional transit in 'Motor City'

    Studies suggest that urban fiscal crises trigger the institutional separation of strategic services from general purpose municipal functions. Traditional reformists have highlighted the economic benefits of regional approaches. Global austerity has created fiscal problems for central cities and suburbs alike, transforming the motives for regional solutions. This paper examines how the City of Detroit engineered a new regional arrangement with the surrounding suburbs to raise debt for the delivery of mass transit infrastructure. It represents a dual 'spatial fix' in the form of (i) a 'state territorial fix' providing fiscally stressed municipalities access to municipal bond markets and (ii) a 'speculative spatial fix' that benefits the Detroit growth coalition by linking regional mass transit to the prospect of land-use intensification.

    Cν\nuB damping of primordial gravitational waves and the fine-tuning of the Cγ\gammaB temperature anisotropy

    Damping of primordial gravitational waves due to the anisotropic stress contribution owing to the cosmological neutrino background (Cν\nuB) is investigated in the context of a radiation-to-matter dominated Universe. Besides its inherent effects on the gravitational wave propagation, the inclusion of the Cν\nuB anisotropic stress into the dynamical equations also affects the tensor mode contribution to the anisotropy of the cosmological microwave background (Cγ\gammaB) temperature. Given that the fluctuations of the Cν\nuB temperature in the (ultra)relativistic regime are driven by a multipole expansion, the mutual effects on the gravitational waves and on the Cγ\gammaB are obtained through a unified prescription for a radiation-to-matter dominated scenario. The results are confronted with some preliminary results for the radiation dominated scenario. Both scenarios are supported by a simplified analytical framework, in terms of a scale independent dynamical variable, kΡk \eta, that relates cosmological scales, kk, and the conformal time, Ρ\eta. The background relativistic (hot dark) matter essentially works as an effective dispersive medium for the gravitational waves such that the damping effect is intensified for the Universe evolving to the matter dominated era. Changes on the temperature variance owing to the inclusion of neutrino collision terms into the dynamical equations result into spectral features that ratify that the multipole expansion coefficients ClTC_{l}^{T}'s die out for l∟100l \sim 100.Comment: 24 pages, 8 figure

    Financing health care in high-income countries

    The main lesson from the experience of high-income countries with health care financing is a simple one: financing reforms should support the ultimate goal of universal coverage. Most high-income countries started with voluntary health insurance systems, which were then gradually extended to compulsory social insurance for certain groups and finally reached universal coverage, either as nationwide social health insurance schemes or as tax-financed national health services. The risk pooling and prepayment functions are essential. Moreover, the revenue collection mechanisms, whether as general tax revenues or payroll taxes, are secondary to the basic object of providing financial protection through effective risk pooling mechanisms. The experience of high-income countries indicates that private health insurance, medical savings accounts, and other forms of private resource collection are supplementary methods for increasing universal coverage.
